Hi Eric,

Some web pages will hog resources regardless of what you do, and RAM has nothing to do with it. This will definitely bite someone who leaves pages or tabs open in the background for long periods.

I can reproduce this on demand with Safari or FireFox if I leave the Amazon home page open in the background. I had the same thing happen while tracking election returns during the US 2018 mid-term elections. The elections page I found was excellent with data, but I was running my MacBook Pro on battery and the charge level was plummeting, the same as when I leave Amazon open. When I closed that page, the battery drain reverted to normal, and Activity Monitor returned to normal CPU and energy use patterns. When I worked in law enforcement, we called that a "clue."

I used Activity Monitor to verify that certain sites were a problem, just as you have done. Outside of convincing web developers to do a cleaner job of coding, all you can do is see what sites are the worst and ask your Lady to close unused tabs if possible.
